BLE security

I don't fault Bluetooth SIG for wanting to drive the new standard like Bluetooth Low Energy to be used as broadcly as possible thus not incorporating the device-level security from the day one.

But protecting security and privacy of devices and data coming out of the devices should be the heart and soul of what makes Bluetooth Smart truly "smart" ...No?

Retro-fitting is always a hack

I see it in standards all the time. Retro-fitting a feature that was not considered at inception always results in a hack which never quite works and invariably comes back to bite. Retro-fitting something as important as security is not something one should be doing. IMHO of course ...

@tpfj, I wonder about that, too...

But in Bluetooth SIG's defense, BLE -- now getting desinged into such a variety of products -- needs to answer different requirements of end products.

Perhpas, BLE's security issue is a result of BLE's own success?

I am sure that BLE is now getting into palces the SIG hand't thought about before.

How far are they planning to take BLE?  I'm not real comfortable with the driver/hacker next to me on the freeway being able to tell my car to reboot.  Call me old fashion, but sometimes wires are worth the weight and extra cost.

Security is a big issue, but frankly so is reliability with anything wireless. A little interference from Wi-Fi in the back seat or something and suddenly a car subsystem acts funny....hmmmm

@Rick, it is true. Reliability is a big issue, when it comes to anything wireless.... But when I asked several experts about interference issues of BLE, I got their answers saying that they are little concerned. But security? Yes, they are worried.

@DouglnRB, I am not sure. But my unerstanding is that they will put in some sort of mechanism in the BLE spec that would allow certain systems to use public key exchange such as Diffie-Hellmann.

Security should of course be a concern, but I think reliability is a far bigger concern. Having said that, I recently saw an episode of a TV drama in which a murder was committed by a hacker who remotely commanded his victim's airbags to deploy, causing a fatal crash. Food for thought as we march toward wireless connectivity in cars.

@AZskibum, understood.

From an engineer's point of view, you think remotely commanding airbags is feasible. Correct?

@rick , bluetooth uses frequency hopping which has high reliability against intereference.

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
